Background: Renal stone disease is common and can cause emergency presentation with acute pain due to ureteric colic. International guidelines have stated the need for a multicentre randomised controlled trial (RCT) to determine whether a non-invasive outpatient (shockwave lithotripsy [SWL]) or surgical (ureteroscopy [URS]) intervention should be the first-line treatment for those needing active intervention. This has implications for shaping clinical pathways. Read More

Extracorporeal shockwave lithotripsy (SWL) results in a lower stone-free rate (SFR) for ectopic kidneys when using the standard technique, directing the shock wave from the same side of the stone; however, this may not be the optimal approach when the ectopic kidney is located more medial and anterior than the normally positioned kidney. Thus, contralateral coupling where waves come from the opposite direction may result in a better outcome. We tested the feasibility and outcome of contralateral coupling during SWL for stone in ectopic kidney. Read More

Background and aim of the work Patients with neurogenic bladder (NB) have an increased risk of developing bladder stones due to bladder catheter, incomplete bladder emptying, recurrent urinary tract infections, and immobilization. In these patients, minimally invasive treatments are usually adopted, as noninvasive extracorporeal shockwave lithotripsy is limited by the risk of not clearing all stone fragments, and open surgery is usually discouraged. The aim of our study was to present our experience with trans-urethral cystolithotripsy (TUCL) in patients treated by a tertiary referral center for NB. Read More

Jackstones are stones in the urinary tract that have the characteristic appearance resembling six-pointed toy jacks. They are nearly always reported to occur in the urinary bladder, and the occurrence in less capacious renal pelvis is unusual. We report a solitary, typical jackstone in the renal pelvis without significant outflow obstruction that was successfully treated with retrograde intrarenal surgery followed by extracorporeal shockwave lithotripsy.

Pretreating the kidney with 100 low-energy shock waves (SWs) with a time pause before delivering a clinical dose of SWs (Dornier HM-3, 2000 SWs, 24 kV, and 120 SWs/min) has been shown to significantly reduce the size of the hemorrhagic lesion produced in that treated kidney, compared to a protocol without pretreatment. It has been assumed that a similar reduction in injury will occur with lithotripters other than the HM-3, but experiments to confirm this assumption are lacking. In this study, we sought to verify that the lesion protection phenomenon also occurs in a lithotripter using an electromagnetic shock source and dry-head coupling. Read More

Percutaneous nephrolithotomy (PCNL) has wide variability in the methods of renal access. In many centers, this is done as a separate nephrostomy procedure by interventional radiology, while other urologists gain initial access themselves during the PCNL. We aimed to characterize these trends to confirm the need for continued training in this aspect of PCNL. Read More
